摘要

热污染可以通过降低导线的电阻来实现。本研究的主要方法是对超导陶瓷进行改性。制备了由YBa2Ca2Cu2.8(Ag, Hg)0.2 O7-δ超导体陶瓷和环氧树脂组成的复合样品。采用磨砂机四探针技术和基于迈斯纳效应的非接触感应技术研究了烧结陶瓷和复合材料样品的超导性能。结果表明:在环氧聚合物中加入陶瓷超导粉末作为填料制备的复合样品中，陶瓷超导前驱体填料的Tc均未降低;观察到一个非常微小的变化。发现银离子或汞离子部分取代铜离子改变了超导性质。此外，使用复合材料的优点是提供高效率和低损耗，这并没有阻碍其应用的发展。

Preparation and study of a superconducting composite based on superconducting ceramic system

Heat pollution could be through decreasing the electrical resistance of wire conductors. The main approach of this research is to modify the superconducting ceramic. The composite samples consisting of YBa2Ca2Cu2.8(Ag, Hg)0.2 O7-δ superconductor ceramic and epoxy have been prepared. The sander four probe techniques and contactless induction based on Meissner effect were used to study the superconducting properties of sintered ceramic and composite samples. The results showed that in all composite samples which were prepared by the addition of the ceramic superconducting powder as filler to the epoxy polymer, there was no decrease in the Tc of ceramic superconductor precursor filler; a very slight change was observed. The partial replacement of Cu ion by either Ag or Hg ions was found to modify the superconductive nature. Also, the advantage of using composite material is providing a high efficiency and low loss, which have not impeded the development of its applications.
